WASHING-MACHINE TUB.

Application nled February 6, 1925. Serial No. 7,826.

My invention relates to washing machine tubs. The invention has special reference to the construction of the tub from metal, and in its formation the utilization of the material of the metal shellA to provide baffle members, viz,ithe impressing from the metal body, the necessary and required battles.

The invention includes the fa'shioning of a tub including baffle members Without the necessity of attachingbale members tothe interior of the shell, also the special fashioning of atop closure member from a sheet metal body adapted for 'union detachably with the main tub shell, and in connection with which a central clearance opening is provided.

The invention further includes the provision of an upstanding centrally disposed bale member of novel form and construction.

The invention also includes the fashionin" of balie members in conjunction with the tub shell to provide .truncated ridge members continuously extended from an initial point above the bottom of the tub and continuously extending to substantial proximity to the centrally disposed baille member.

The invention includes a central drain means in association with the balile member.

In a further respect, this invention provides a novel method of washing clothes in a more eicient and thorough manner than heretofore employed.

This and other features vof the invention and the novel method referred to, will appear more fully in the following detailed description when read in connection with the accompanying drawings, and will be pointed out in the appended claims.

Referring to the drawings:

Fig. l, is a vertical sectional view through the center of the tub, except that a battle member is shown complete in full lines.

Fig. 2, is a vertical sectional view, through the center 0f the bottom portion of the tub and attachment members thereto, and showin a partial central sectionall View of the ba e member.

Fig. 3, is a similar view to that shown in Fig. 2, except with respect to the adjustment of a movable part of the structure shown.

Fig. 4, is a top view of the tub.

Fig. 5, is a side elevation of the tub, andv Fig. 6,' is a bottom view of the tub.

Referring to the drawings, 10, is a main shell preferably developedy from a single refers generally to baffle members impressed for projection within the bod -of the tub shell, comprising vertically an horizontally extending reach portions thereof, respectively indicated as: vertical reach 16, and horizont-al reach 17. The bale members are preferably fashioned to present ridge formation consisting in an expanded base portion and a contracting a ex as shown.

18, is a shell which constitutes the main body of a centrally disposed bale member, the same being seated in conjunction with case frame member 19, the latter being detachably related to the bottom of the tub by means of a threaded union thereof, with upstanding member 20 associated with or connected with bottom plate member 12. Cast member 19, is fashioned with' an openin'g as 21, adapted for entry therethrough of a stem or plunger member associated with drain means for the tub. The bottom edge of cast member 19, is arcuately recessed at spaced intervals as indicated in 21a thereabouts to afford drain way entry means from the main body .of the tub to the interior of the general combination structure. The main functioning purpose of baffle member 18, is for co-operation with the specially formed baiile members to the end of producing a certain circulated action, viz, a progressive spiral course of the liquid content, progressively active throughout the interior circumference of the tub as distinguished from cross` currents passing through the center thereof.

A drain means is rovided in conjunction with the baffle mem er and the bottom of the tub, comprising a plug for opening or closing drain way 13, which includes a stopper element 22, fixed to a screw plug 23, the latter threaded for projective union with member 20 of bottom plate 12. The plug or stopper member is raised or lowered through the action of a stem 24', projectivel related to said plug and turnable throug and by means of a cap member S25, fixed to the upper end of, the stem member whereby effect citherprojection or elevation of the stopper member. A coil Spring member 26, is compressively and cxpansively related to the stem member and the top closure late 27, at the top of battle member 18, where y, normally ca member 25, will be heldin closed seated re ation upon the top. ot' battle member i8, to prevent the entry o water content of the tub.

Tub top closure member- 28, is preferably' fashioned on general cur-ved lines for strengthening purposes and is provided with the necessary outer marginal formation to facilitate ready detachable union with the top edge of the main tub shell.

rlhe top is provided with an extended central opening and in the general fashioning, the inner marginal portion of the top is down-turned substantially in the vmanner shown in the drawing. Within the central opening of the top closure member, a suitable closure member for said opening may beprovided; however, as this closure member does not constitute any part of the present invention, such member is not shown.

The tub herein disclosed, is designed for detachable seating in conjunction with a reciprocating member whereby reciprocatory action is imparted to the tub.

We will not further extend the description over that above written with respect to the operation of the device as the inventionlies only in a small degree in the matter of an operative part to wit, the drain, but generally to the ashioning of the tub and the relationing of baile members theren,`to a centrally disposed baffle member. However, we desire to note that, because of the special formation of the baiie members to present vertical and lateral projective form and the inter osition of the expanded central baffle` mem er, as the tub is reciprocated and agitation of the water contentis `developed therein, a progressive spiral activity of such water content is produced that causes the materials to be Washed, to be continuously faceexposure to the water content, thereby` greatly facilitating and hastening the washmg actlon.

What I'claim is: p v

I l. iln a washing machine tub comprisinga sheet metal body, a plurality of spaced battle members integral with said body, each of said baffle members comprising a vertically extending reach member and a horizontally extending reach member impressed inwardly from the side and bottom of the body 'respec-- tively, a conica battle member centrally disposed within said body and projecting up# wardly to a point adjacent the upper portion ofthe tub, and atop for said body extending inwardly from the upper edge thereof a distance suflicie'nt to-cover the vertically extending reacli members. j

2. it washing machine tub having a metallic body and a plurality of spaced baille members withinsaid body, each otsaid battle members comprising a vertically'extending reach member and a horizontally extending reach member,V said reach members having an j expanded base portlon and a contracted apex, and the external or working surface of said battles being substantially continuous.

3. A washing machine tub comprising a sheet metalbOdy and a plurality of spaced 'baille members termed within said body and integral therewith, each of said baille mem- .bers comprising a vertically extending reach member and a horizontally extending reach member impressed from the side and vbottom .of the body, the sides of the baille members converging away from the wall of the body and connected by a rounded edge, the Working surfaces of each of said-battle members beingsubstantially continuous.

I In testimony whereof- I at'rx signature.
